Reduction in ground vibrations by using shaped landscapes
(2014) In Soil Dynamics and Earthquake Engineering 60(May). p.31-43- Abstract
- Reduction in traffic-induced ground vibrations by the use of shaped landscapes is investigated here by shaping the landscape surrounding a high-tech facility, using the landscape thus produced as a wave obstacle. The effects of the geometric parameters of a shaped landscape were examined in parametric studies. An architectural landscape design was also investigated in terms of its effectiveness in reducing traffic-induced ground vibrations. Finite element models, analysed in the frequency domain, were employed. The models involve a layer of soil and the underlying bedrock. It was found that anywhere
from an appreciable reduction to an appreciable amplification of the vibrations produced can occur,depending upon the geometric...
